Application led August 27,

ToV all whom it may concern.:

Be it known that l, EMIL Meneer., a olli; zen ofthe' Swiss Confederation, and resicling n.1', Berne, Switzerland, llave invented certain new and useful improvements in Dislriesliers, of which the 4following is a speC'iicet-ion.

, My invention relates lo machines for rinsing iiiensils, Crockery and lie like, n, primary object is to provide suoli a inaoliine which comprises in e teni; for liolcling rinsing Water e, jonrnalecl eoniey'er Worin, a part of whose periphery projects into the water, enel which is elizfirgecl et its one end Willi the utensils to be cleaned which, when the Worin rotates, pese along turngroeie e nirection opposite to Jolie direction oi1 rotation of the worm and then leave the at its olier encl. I

@ne illust-relive embodiment oi' iny invention is represented by Way of exemple in the accompanying drawing, wherein Figure l is an elem-aliena n pari: vbeing broken away, showing one eonsrneion mtif'iniproyeei machine, Fig. 2 a longitudiseeiion rlnongli the seine, Figs. 3 and l are (leinil views and, Fig. shows other fletails.

The slide under the inrlnenoe or e spring tending to nj ss it against the periphery of n cam 2l inst on 'die shaft 8. Further, alle easing 2 lies in its side nearest'ilie Worin 17 en oval aperture located near that encl -o? the eas ing :it which the oli-.iin gearing and cranklienclle are provided. The aperture 25' is oonnclefl by n shower pipe-26 whichl is een nee'tecl to liot Water pipe 27. fl pipe'QS, connected oy e, branch 29 with the lowestimrt of the ank l, passes vertically-through the bot-toni of the container il and enters into the lower half of the. easing i., the joint between this pipe and the bottom' of the ooneiner being packed watertight. Tliepipe leperefl eonioally below the braneli'f; f Wni ^ll1 exactly iis the conical end is provided with a' 'nenfllev 30, mi is open botli ends slius ori' A Q in the position shown in .Je branch simillmneoireifv s rves ,es owerlloiv pipe lor trink. 'li drain pipe 32 is inserted into lie lowest peril lie Container ll. The. illustraceel machine is particularly ifnnteel for rinsing fiat utensils or crookeiy,

with hot water. The water in the tank may be heated or kept warm by heaters 33 prolvided in the tank. 1n the said position of slide 20 sidewise and downward, so that the plate on the board 19 can slide down the latter and fall into the first space between two turns of the worin 1. On the shaft 8 being rotated farther the slide 2O is lifted and only lowered again when the worm 4 has rotated one complete revolution. A. second plate placed in the meantinievon the board 19 can then fall into the end of the worm, while the irst plate is now in the second space between two turns. In this manner the plates to be lcleaned are individually inserted into the machine which prevents the plates being broken withoutimpairing the speed of the operation, as the worm can be kept in constant rotation.

The plates located in the lower part of the worm projecting into the water are con- .stantly rotated in a direction opposite to the direction of rotation of the worm, as indicated by the arrows in Fig. 5. Conselquently, all parts of the plates come into contact with the rinsing water. In addition, they are brushed by the brushes 11, and even when plates of various diameter are being rinsed each part of the same is repeatedly brushed when passing along the worm in consequence of the plates rotating when care is taken that the brushes are broad enough to brush the plates beyond their centers. When one plate has traveled entirely through the worm 4: it is niet by a pin 34 provided on a strip 35 (Fig. 2) attached to the end of the last turn of the worm, is lifted out ot' the water and conveyed through the aperture 25 of the casing 2 onto the one end of the worm 17. `When passing through the aperture 25 each'plate is liberated from rinsing -water adhering to it by hot water issuing from the shower pipe 26, and thc plate which is otherwise heated by the rinsing water is raised to sucha temperature 'that it arrives almost dry at the other ,end of the worin 17. is so small and the clearance between it-and the casing 2 and the adjacent end walldf. the container 11 is so small that the plates cannot fall down into the lower part of the container, but lying against the shaft 16 and against a journaled rod 36 running alongone of the walls et the container 11 can be conveyed by the worin 1 7 to the other end. The end wall of the container 11 opposite moved.

The diameter of the worin 17 plates issue from the worm 17v they abut against this strip and slide with their hollow sides upward onto a shelf 39 (Fig. 1) projecting outside the container 11 below the aperture 37, from which they can be re- After the rinsing is finished the water is run out of the tank by lifting the rod 3l, the residues or" food collected at the i bottom of the tank, or like substances, being for the most part washed away` Water which drops from the washed plates collects at the bottom of the container 11 and runs away 'through' the pipe 32.-

As the brushes are worn away rather rapidly in hot water, z'. e. as the bristles or rootsl of which the brushes are made are readily bent, the sleeves 10, carrying the brushes, must be rotated slightly from time to time, this being done by hand without ditliculty; care must, however, be taken that the sleeves 10 are notso loose on the spokes 5 that they automatically rotate during the rinsing operation.

I claim 1. A dish-washer having a rinsing-water f tank; a conveyer-worm in which are mounted brushes and the worm-threads of which are pervious to water, and la oraminated covering for said conveyer-worm; the space between the latter and its covering being ofy sui'ticient size tov receive the dish, which is setin .rotation ,during its travel along the worm. c

2. In a rinsing-machine, the combination with a tank containing water, of a conveyor worm journaled in the tank and having part of each turn in the water in the tank, and a perforated jacket on the worm, the turns ol the worm being perforated.

3. In a rinsing-machine, the combination ot' a casing a part of which constitutes a tank, a conveyer worm journaled in the cas- I ing and having part ofeach turn in the tank, said casing having an inlet at one end of the worin and an outlet at the other end; a board sloping down to the inlet, a spring- `intluencedhslide normally lying below the 'edge of the board at the inlet, and means -actuated by .ne worin for moving the slide to a position above the edge, of the board.

et. 1n a rinsing-machine,ltlie combination with a tank containing water, vof a conveyor worin journaled in the tank and having part of each turn in the water in the tank, and a plurality of brushes journaled in the walls of the'thread of the worm, said walls being pervious to water.v c

5. 1n a rinsing-machine, the combination ,of a casing a part of which constitutes a tank, a conveyor worin ournaledYirnthe'eas--f ing and having part of each turn in the tank, said casing having an inlet at one end of the worm and an oulet a': th other en; a En testimony whereof, 'I afm my signacontane pareille?. t@ the casing, a conveyer Worm journaed in the container, means on the forme? Worm for lfng a utensil through tha outlet to me and of the latter w0rm,` and a shelf on the'containe at fue other end of the atter Worm.
